Brake question
Moved from another post, thought maybe no one saw it as there were no responses to this particular question. I noticed today, when stopped at a light I could hear the electric motor for the brakes...
Forum Discussion
Gas motorhomes use what is called "hydroboost" for brake power assist.
This is a hydraulic system that operates off the power steering pump.
These systems have an auxiliary electric pump to provide boost if the engine is off, and that electric pump is what you are hearing.
It's totally normal.
